Definitions

  • the present invention relates to a firearm 1 comprising a safety trigger.
  • one particular known solution envisages a primary trigger, centrally split to house a secondary trigger protruding from the first; in such device the secondary trigger acts as a release on the primary trigger, inasmuch as situated in a suitable position to be pulled first, while the primary trigger in turn causes operation of the firing device of the firearm.
  • the present invention falls within such context, setting out to provide a firearm with a safety trigger which is reliable and suitable for being produced at an extremely limited cost.
  • figure 1 shows a perspective view of a firearm, according to a possible embodiment of the invention
  • FIG. 2 and 3 respectively show perspective and lateral enlargements of a portion of the frame of the gun in figure 1, in which the trigger is positioned in a blocking configuration;
  • figures 6 and 7 show partial cross-sections corresponding to figure 5, in which the trigger is respectively positioned in an engaged configuration and in an activation configuration;
  • FIG. 11 shows a perspective view of a support body according to one embodiment.
  • reference numeral 1 globally denotes a firearm.
  • the present invention will be illustrated below on the basis of a gun, in particular a semi-automatic gun.
  • Other forms of embodiment of the present firearm in fact envisage use of the aforesaid safety trigger with revolvers, rifles, automatic rifles and the like.
  • the firearm 1 comprises a firearm frame 2 and a firing device associated to such frame 2.
  • the firearm frame 2 supports the firing device, advantageously in such a way as to at least partially housing it.
  • the firing device comprises at least one transmission body 22 for the movement of at least one firing pin towards a firing chamber (not shown) of the firearm.
  • the transmission body 22 comprises a lever which extends proximally to interact with the firing pin or with a hammer, for example by means of a translation.
  • distal will be used to indicate the components positioned towards the muzzle 38 of the firearm; vice versa the term “proximal” will be taken to mean the components of the gun positioned on the opposite side of such muzzle 38, that is to say close to or towards the butt of a rifle or towards a grippable portion 40 of a gun.
  • the firearm 1 further comprises at least one trigger 4, connected to the firearm frame 2 by means of a mobile support body 6. This way, the trigger is rotatable in relation to the frame 2 between a blocking configuration, in which the movement of the trigger 4 to activate the firing device is prevented, and an engaged configuration of the trigger 4, in which it engages the support body 6 in movement .
  • the trigger 4 rotates in relation to the frame, and preferably also in relation to the support body 6 which in this phase is advantageously substantially static.
  • the trigger 4 is suitable for being further operated from the engaged configuration to an activation configuration of the firing device. This way, the advancement of the firing pin towards the firing chamber is for example promoted.
  • the trigger 4 comprises at least one blocking appendix 14' , 14" which, in the engaged configuration, joins it to the support body 6.
  • the blocking appendix 14' , 14" is radially distanced in relation to a primary rotation axis X of the trigger 4 in relation to the support body 6, so as to intercept such body and make it integral with the trigger in the subsequent movements of the latter.
  • the blocking appendix 14', 14" is suitable for abutting against an abutment pin 24 integral with the firearm frame 2.
  • the blocking appendix 14', 14" is shaped in such a way as to at least partially housing the abutment pin 24, being preferably in a complementary manner to its outer profile .
  • the abutment pin 24 defines a secondary rotation axis Y for the trigger 4.
  • the firearm 1 comprises a pair blocking appendices 14', 14", for example asymmetric, distanced from each other so as to create a space 16 for the at least partial housing of the support body 6.
  • the support body 6 is at least partially housed in the trigger 4 in at least one of its configurations; preferably, substantially the entire portion of the support body coming out of the firearm frame is completely contained in the trigger, for example during all its functioning configurations.
  • the trigger 4 is connected to the firearm frame 2 in a roto-translatory manner.
  • this embodiment envisages the trigger being hinged to the support body 6 and the latter being connected in a translatable manner to the firearm frame 2.
  • the trigger 4 is connected to the firearm frame 2 in a rotatable manner around two separate axes X, Y.
  • the trigger is mounted rotatably in relation to the support body 6 around the primary rotation axis X, while such body 6 is hinged to the firearm frame 2 around the secondary rotation axis Y, for example passing through the abutment pin 24.
  • the secondary rotation axis Y is substantially parallel and separate from the primary axis X.
  • the trigger 4 is therefore hinged to the support body 6 at a first end portion 6' of the latter, while a further embodiment envisages that the support body 6 is hinged to the firearm frame 2 at a second end portion 6", for example opposite the first 6' .
  • the trigger 4 is mechanically connected to the firearm frame 2 by means of a blocking element, advantageously integral with the trigger 4.
  • the blocking element comprises at least one heel 12' , 12" connected to and extending from the trigger 4 for example rearwards or proximally.
  • such variant envisages a blocking element/heel which extends advantageously rearwards from the trigger, that is to say in a direction opposite to the front surface 26 of such trigger, suitable for interacting with a finger (usually the index finger) of the firearm user.
  • the trigger 4 is mobile inside an inner compartment 28 of the firearm frame, delimited at the bottom by a frame rim 30. [0035] . According to such variant, when the trigger is in the blocking configuration, the blocking element/heel of the trigger lies in abutment against the frame rim 30 so as to prevent its proximal backward movement.
  • the firearm 1 comprises first return means 8, preferably elastic, which work between the firearm frame 2 and the support body 6 to return the trigger 4 to the engaged configuration. This way, when the trigger is free of constraints, the first return means 8 are suitable for returning it to the engaged configuration.
  • the first return means 8 are guided in a seat 32 performed in the firearm frame 2.
  • a seat 32 extends so as to be incident to a line joining the primary X and the secondary rotation axes Y.
  • the seat 32 is positioned distally in relation to the trigger.
  • the support body 6 comprises at least one thrust tooth 10 suitable for acting on the return means 8.
  • the first return means 8 comprise an elastic portion 34, such as a helical spring, which pushes against the firearm frame 2, and a portion of interaction with the support body 6 (preferably with the thrust tooth 10) which works between the elastic portion 34 and such body.
  • an elastic portion 34 such as a helical spring
  • second return means 18 for example elastic, are also envisaged, suitable for returning the trigger 4 to the blocking configuration.
  • the second return means 18 comprise a torsion spring.
  • the elastic constants of the first 8 and of the second 18 return means are different.
  • the force of action of such means may be selected so that the conversion between the engaged configuration and the blocking configuration is harder than the passage from the blocking configuration to the engaged configuration.
  • the second means 18 are at least partially housed in a split or fork 20 performed in the trigger 4.
  • the fork 20 terminates in the space 16 for the at least partial housing of the support body 6.
  • the trigger 4 is mechanically connected to the transmission body 22 of the firing device.
  • the transmission body 22 and the support body 6 are both hinged to the trigger 4, preferably presenting the same rotation axis X to the trigger 4.
  • the present invention also relates to a method of activation of a firing device of a firearm 1.
  • Such method comprises a step of rotating a trigger 4 in relation to the firearm frame 2 by means of a mobile support body 6, between a blocking configuration, in which the movement of the trigger 4 to activate the firing device is prevented, and an engaged configuration of the trigger 4, in which it engages the support body 6 in movement .
  • Such method further comprises a step of operating the trigger 4 from the engaged configuration to an activation configuration of the firing device.
  • the step of activating the trigger 4 comprises a step of rotating the trigger 4 around two separate and preferably parallel axes X, Y.
  • the firearm which present invention relates to provides a safety trigger which is highly reliable and suitable for being produced at an extremely limited cost.
  • the firearm which present invention relates to makes it possible to independently select the blocking force of the trigger and the force needed to fire.
  • the activation of the firing device takes place by means of a complex and orchestrated movement. This way, an impact casually directed acting on the trigger, for example following a fall, is not sufficient to cause an accidental shot.
  • the firearm described makes it possible to considerably reduce the dimensions of its components, particularly given the optimisation of space inside it.
  • the firearm which the present invention relates to is extremely solid, and the simplicity of interaction of its components makes it possible to prevent both accidental firing and undesired blocking of the firing device.
